In most situations finding the MAC address of a wireless device is fairly straightforward. However there are some things like smart TVs, IOT devices, gaming consoles, etc. that either don't display that MAC or have it hidden in a mess of on screen menus. This device broadcasts a wireless network without a password. Connect any wireless device to it and once the connection is made the MAC address of the device will be displayed on the small OLED screen.
Spin two DC motors or step one bi-polar or uni-polar stepper with up to 1.2A per channel using the DRV8833. This motor driver chip is a nice alternative to the TB6612 driver. Like that chip, you get 2 full H-bridges, but this chip is better for low voltage uses (can run from 2.7V up to 10.8V motor power) and has built in current limiting capability. We set it up for 1A current limiting so you don't get more than 2A per chip, but you can also disable the current limiting, or change it to a different limit!
Here's a guide to quickly and easily adding exciting, colorful lighting effects to your props. Using the accelerometer, speaker, and NeoPixel LEDs built into the Circuit Playground, you can have sounds and lights for idle animations, along with two different effects triggered by waving and striking your foam sword, cosplay blaster, magic wand, and more.
